The correction of one error in the court below does not deprive the appellate court of the power of examining further into the record, and correcting any other material errors which may have been committed by the inferior court. There is certainly no rule of law--nor any practice--nor any decision of a court--which even questions this power in the appellate tribunal. On the contrary, it is the daily practice of this court, and of all appellate courts where they reverse the judgment of an inferior court for error, to correct by its opinions whatever errors may appear on the record material to the case; and they have always held it to be their duty to do so where the silence of the court might lead to misconstruction or future controversy, and the point has been relied on by either side, and argued before the court. In the case before us, we have already decided that the Circuit Court erred in deciding that it had jurisdiction upon the facts admitted by the pleadings. And it appears that, in the further progress of the case, it acted upon the erroneous principle it had decided on the pleadings, and gave judgment for the defendant, where, upon the facts admitted in the exception, it had no jurisdiction. We are at a loss to understand upon what principle of law, applicable to appellate jurisdiction, it can be supposed that this court has not judicial authority to correct the last-mentioned error, because they had before corrected the former; or by what process of reasoning it can be made out, that the error of an inferior court in actually pronouncing judgment for one of the parties, in a case in which it had no jurisdiction, cannot be looked into or corrected by this court, because we have decided a similar question presented in the pleadings. The last point is distinctly presented by the facts contained in the plaintiff's own bill of exceptions, which he himself brings here by this writ of error. It was the point which chiefly occupied the attention of the counsel on both sides in the argument--and the judgment which this court must render upon both errors is precisely the same. It must, in each of them, exercise jurisdiction over the judgment, and reverse it for the errors committed by the court below; and issue a mandate to the Circuit Court to conform its judgment to the opinion pronounced by this court, by dismissing the case for want of jurisdiction in the Circuit Court. This is the constant and invariable practice of this court, where it reverses a judgment for want of jurisdiction in the Circuit Court.
